Problems solved by technology

[0002] During the processing of the existing insulating cardboard, the waste paper powder produced by sawing and grinding, the fiber length of which can no longer meet the requirements of pulp and paper making, generally can only be used as an additive to coal for boiler combustion, etc.
The high purity of its fibers is a rare raw material, and the high price of raw materials makes it more intuitive to cause objective waste of resources and economic losses caused by waste abandonment

Embodiment Construction

[0006] Making charcoal from insulating cardboard processing waste paper powder and its technology is realized in this way: add dry insulating cardboard processing waste paper powder and clean clay to pure water and mix them thoroughly. Their weight ratio is: insulating cardboard processing 86 parts of waste paper scraps, 8 parts of clean clay, and 6 parts of pure water; put the mixed raw materials in a special hollow hexagonal tube mold, and press them under the pressure of 30KG / square centimeter according to the quantity; the dimensions are controlled at The length / width / height are all 50 mm, the internal hole diameter is 20 mm, and the wall thickness is 25 mm; the pressed blank is placed in a firing kiln, and the finished product is obtained by firing, flame extinguishing and cooling, and is packaged into bags to make commercial charcoal that can be used as fuel for hot pots.

Abstract

The invention relates to wood charcoal produced from processed waste paper scraps of insulating paper plates and a producing process thereof. The producing process comprises the steps of: adding the dry processed waste paper scraps of the dry insulating paper plates and clean clay into purified water to be mixed and stirred fully; placing the well mixed raw material in a purpose-made hollow mould for compression molding under pressure; putting blanks obtained after the compression molding into a firing kiln to be fired, flame-hardened and cooled so as to obtain finished products; packaging the finished products with bags to form commercial wood charcoal which can be used as hotpot fuel. The wood charcoal produced from the processed waste paper scraps of the insulating paper plates and the producing process thereof, disclosed by the invention, have the advantages of simple processing way, small floor area, low equipment investment and high commercial value of the product.

Description

technical field [0001] The invention relates to the reuse of waste paper scraps produced in the process of insulating cardboard processing which cannot be used for pulping and remanufacturing, in particular to the technology of making commercial charcoal with waste paper scraps. Background technique [0002] The fiber length of the waste paper powder produced by sawing and grinding during the processing of existing insulating cardboard can no longer meet the requirements of pulping and papermaking, and generally can only be used as an additive to coal for boiler combustion. The high purity of its fibers is a rare raw material, and the high price of raw materials makes it more intuitive to cause objective waste of resources and economic losses caused by the waste of waste. In order to fully tap the commercial value of waste paper scraps, further utilize resources, reduce the consumption of forest vegetation, and find a more reasonable way to use waste paper scraps, it is the ...
